I’ve never used a veg for these purposes and I’m not planning to. I would definitely not recommend it to anyone, and I would recommend be very mindful of the hygiene of any objects you decide to insert for whatever reason- speaking from experience here, UTIs are no fun.
Most people don’t use vegetables for this afaik.
That aside, the only girl who ever confided in me that she used a veg (a banana btw) also said she put it in a condom. She said she would bin it all afterwards and this sounds like what someone reasonable enough would do. I’d be grossed out if I was to eat something used for that and I’d feel awful to have my family eat something used that way. Just no.
